Have you ever wondered how your site stacks up against its competitors? Most people don’t make their traffic stats available to the general public, though doing so can attract advertisers…
That’s what Compete.com is for. They use some secret methods to estimate site traffic, and allow you to compare sites against each other. It’s accuracy is pretty good too. I compared a graph of Webmaster-Source’s unique vistors over the course of a year with the same time frame from Google Analytics. The results were close enough.
It’s dead-easy to use Compete. Just input your domain and a competitors’ or two. You get a graph like this back:
The default graph shows unique visitors over a period of one year. You cna switch it to pages per visit, “attention,” average stay, or if you pay for premium service, pageviews. It also offers some other interesting figures, such as high-traffic search keywords and growth. You can embed graphs on your website too, such as on an “Advertise Here” page.
It’s on, Michael. 
I did it and then immediately depressed myself!
I have a LOT of work to do now.
Haha, well, it depresses me too. It's hard to keep up with Michael from Pro Blog Design. We tend to be neck-and-neck, then he has all these crazy traffic spikes…
Are these statistics accurate enough to rely upon ??
